Seismic activity in Australia is categorised as low to moderate. However, the rate of the deformation of the Australian continent is faster than other stable intraplate regions, such as Eastern North America and Africa. Adelaide region is the most seismically active zone in the Australian continent. Therefore, seismic hazard analysis of the Adelaide region is needed to improve the accuracy of seismic hazard predictions. Probabilistic seismic hazard analysis (PSHA) incorporating Monte Carlo simulation is selected in the present paper. This method has several advantages i.e. simple, fast, flexible, and robust. Results of the analysis suggest comparable results with previous studies. Furthermore, two main threats are identified in the de-aggregation for the Adelaide city. Due to the limitation of strong magnitude event and the scarcity of the seismic event, further work is suggested for improving the estimates by extending the seismic catalogue i.e. incorporating neo-tectonic and paleo-seismic studies.
